Is there an obvious method to truncate a float? or reduce the precision of it for display?
i want these
1.851852
1.323412
2.452553
40.34221
to become these...
1.851
1.323
2.452
40.343

Easy
floor(1.851852 * 1000) /1000
1.851852 * 1000 = 1851.852
Floor(1851.852) = 1851
1851/1000 = 1.851
But round() can be used 2.
If you want it to be 1.852 that is nearest whole.

Ok... so i tried this but when I render it to a text field it just stacks on the extra 0z.

Yea I noticed that floats in text boxes/canvas will create extra 000.
Haven't tested this but, since its text, the number can be converted to a text string instead.
so a method would be like:
input = 1.851852
val_1 = floor(input)
val_2 = round((input - val_1)*1000)
val_1= 1
val_2= 852
new_float = '' + val_1 + '.' + val_2
setattribute(text_object,'content',new_float)
new_float = "1.852"
but displayed: 1.852
so depending on how many values u want after .
then change *1000 to *100 if u want just 1.85
but the new_float can't be used for any math only text display since its now converted to a text_string by doing the + '' .
but this is how i created the displaying of arrays in the log_message module.

100% works this way. you are the man!
I realize now it seems easier to just put this in a monitor object and set the precision using that. I wish we knew more about these under the hood. I figured text objects use less memory.

lol... ok i always speak so soon... i'll see if i can come up with a solution for this but if you get a value like 0.005 it flattens the number to 0.5. not holding the number of characters. Just gonna go with using a monitor in the meantime.

Yea use Monitor if you only gonna display a single float value.
Text object trick is for when mixing text and floats.
0.0x values in text will require another “for loop” trick.
I can show when i got time.
Busy atm with my ableton live control project
